Argentina have made an enforced change to their side before squaring off against England on Saturday.
The late change comes after Argentine mainstay full-back Joaquín Tuculet was injured hours before kick-off.
Speedy outside back Santiago Cordero moves from wing to full-back with Northampton Saints player Juan Pablo Estelles coming onto the wing in place of Cordero. Gabriel Ascárate will take the number 23 jersey.
Estelles will earn his third Test cap for the Pumas when he runs out against England.
